From my research this is what I've concluded on how to extend the life of the DCT.
-always drive in Manual mode with sport button pressed
-never use the kick down switch at the end of the accelerator pedal
-don't floor the throttle at low revs and high gear
-Don't do too many back to back launches
-Don't use a piggyback without an accompanying flash
and it should be OK.
Guess I'll find out when I get my Vargas turbo installed.

Agreed with most of the above except one. You mentioned don't use piggybaack without accompanying flash. why is that?

The DME reports engine load to the trans controller, trans controller uses this info for plate pressure etc. with a piggyback, the DME reports stock load values because that is what it sees. Depending on the actual engine load, it could be producing enough torque to overcome the friction because the Trans controller is not increasing pressure (because it believes it is only attempting to hold stock torque levels)

These GT-R do 100-200 in 8-9 sec, 6,1 sec is more like 800HP 100-200 in 6,1 sec is a high 9s GT-R

8-9 sec LoL ) There are http://www.drive2.ru/l/947328/ GTR 486hp with cobb st1 540Hp, run 100-200 6.2s
LCI GTR 540hp run 100-200 6,1 ( best time ) Did you have GTR ? Try to measure 100-200 time on LCI.
